Generally speaking spells do not require a wizard to be able to see his target - his sense of magical awareness enables him to direct the spell. This means, for example, that a wizard can cast spells in front or behind him, and against targets that are obscured by other troops or terrain.

Some spells do require that a wizard can see his target. These are spells where the wizard projects or throws a fireball or some such sorcerous missile. In this case the casting wizard must have a clear view of his target, or a clear view of the spot from which a spell starts to work. In the case of these spells the target must lie within the wizard's 90° arc of sight. These spells are indicated with the words 'Line of Sight' on the spell cards.
